BOX-MACHINE.

SPEGIFIGATION'forining part of Letters Patent No. 731,729, dated. June 23, 1903-. Application filed May 5, 1902. Serial No. 105,898; (No model.)

To wZZ whom it may concern:

Be it known that I, GEORGE R; WYMAN, a

. citizen of the United States, residing at East Walpole, in the county of Norfolk and State carton and to secure such of Massachusetts, have invented certain new and useful Improvements in Box-Machines,

of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention has reference to improvements in box-machines, and relates particularly to that class of box-machines whereby the open ends of boxes or cartons are. closed and the closures secured- The object of the invention isto mechanically close certain end portions of a box or portions in the closed position.

Another object of the invention is to so construct a machine of this character that the mechanism for turning down the cemented portion shall be controlled by the cement or glue applying means.

Another object of the invention is to improve the cementor glue applying means.

Another object of the invention is to provide an ejecting device adapted to eject boxes of different sizes.

The main object of the invention is to generally improve box-machines of the character herein described whereby the closing of the ends of the boxes or cartons and the ejecting of the boxes from the machine are effected.

The invention consists in the construction of the glue-applying mechanism and in its association with its cooperating parts.

The invention also consists in the movable flap-support and in its combination with the glue-applying mechanism.

The invention also consists in the former, its carrying mechanism, and the means for exerting pressure on the closed end of the box.

The invention also consists in the peculiar construction of the former or anvil carryingmechanism the ejecting device,and the means a for actuating the ejector.

The invention also consists in such other novel features of construction and'combination of parts as shall hereinafter be more fully described, and pointed outin the claims.

Figure 1 represents a front elevation of the improved machine. Fig. 2 represents an end view of the same. Fig. 3 represents a plan view of the machine, particularly illustrating the controlling relation between the frame of the glue-applying mechanism and the folder plate. Fig. 4 represents a view of the formcarrier removed from the machine and disclosing the ejector, a closed box being in po sition on the form. Fig. 5 representsa perspective view of a box one end of which is designed to be closed by this machine. Fig. 6 represents a side View of portions of the form and the folder-plate with an open-end box in position to be operated on.

Similar characters of reference'designate corresponding parts throughout.

This machine is designed for use in closing one of the open ends of a box or carton similar to that shown in Fig. 5, having the flaps a a and b c, by closing the flaps down onto a form or anvil, applying glue or cement to the flaps during such closing, and subjecting the v end of the box thus formed to pressure, and finally ejecting the box from the machine.

In the drawings, 5 and 6 represent the side or end frames of the machine, connected at their upper ends by the hood or plate 7 of substantial construction and designed to resist a considerable pressure. Journale'd in' bearings in these frames 5 and G and in the bracket 8 is the main drive-shaft 9, and on this shaft is journaled the sleeve 10, adapted for driving connection therewith by means of any usual form of clutch mechanism furnished with a stop, as 12. On this sleeve 10 are secured the drive-pulleys 13, 14, and 15, and on the shaft 9 are fixed the pressure-cam 16, the ejector-cam 17, and the carrier-actuator cam 18, this latter having dwells 19 and 20 located with registering relation to the active portions of the cams 16 and 17, an acting portion 21, and a return 22.

At the lower portion of the frames 5 and 6 is journaled the rock-shaft 23, having the treadle 24 and the locking-arm 25, adapted to engage the stop 12 and hold the friction mechanism out of engagement with the shaft 9 until said stop is released by the depression of the treadle. Also journaled in the frames 5 and 6 is the shaft 26, having the arm 27, the antifriction-bearing at the free end of which rides on the edge of the pressure-cam 16. Pivotally mounted on studs extending from this arm 26 is the carrier-arm 28, one side of the yoke 29 of which has the depending mem ber 30, in which the stud-shaft 31 is secured, this stud-shaft working through the opening 5 of the frame 5 and being pivotally engaged in a perforation of the arm 32, the slot in this arm 32 working over that portion of the shaft 9 which is between the outer face of the frame 5 and the cam 18 and the slotted end of this .arm 32 having a projecting pin 33, carrying an antifriction-sleeve which works against the edge of the cam 18'. To the yoke 29 of the carrier-arm 28 are secured drawing-springs 34 34, the other ends of which are secured to the respective frames 5 and 6.

The carrier-arm 28 (more fully illustrated in Fig. 4 of the drawings) has the channel 35, in which is freely-movable the block 36, carrying the ejector-rod 37, having at its upper end the spur 38, the downward movement of the block 36 being limited by the stop 39. At the sides of the carrier-arm are secured the steps 40 40, which may be adjustable on their bolts, and on the free end of this carrier-arm is the form or anvil 41, centrally perforated to permit of the working of the ejector-rod therethrough and removably secured to the end of the arm 28 by means of the screw 42 or other suitable securing device. The form 41 is preferably of a size and shape corresponding generally to the inner cross-sectional shape and size of the box to be supported thereby and is removable for the substitution of forms of other shapes and sizes to substantially correspond to the like dimensions of boxes of various sizes and shapes without change in the ejector device, this ejector being designed to act on boxes of any shapes or sizes capable of passing through the machine. The steps 40 are adjusted with reference to the length of the box, or, if desired, the adjustment between these steps and the surface plane of the former may be effected by increasing or diminishing the thickness of the form 41.

The arm 43 has a slotted portion which works over the shaft 9 between the frame 6 and the cam 14 and is furnished with the pin 44, which is engaged within thecam-lip of said cam. At its upper end this arm 43 is pivoted to the crank-lever 45' of the sleeve 46, journaled on the shaft 47, which is fixed in the frames 5 and 6, a stop 48 being provided on said sleeve for limiting the rocking of the sleeve by contact with the frame 6 and this sleeve being furnished with the ejectorfinger 49, the free end of which is designed for engagement with the block 36 of the carrier-arm when said block'is brought to a suitable position.

The fiap-support and turning-down plate 50 has arms which are pivoted in the frames 5 and 6 and has the diagonally-extending finger 51, the stop 52, fixed on the frame 5, being intended to limit the depression of this plate 50 and to act as a support therefor. Other means for movably supporting and sustaining this plate 50 may, however, be used.

From the frame 6 extends the bracket 53, on which the glue or cement reservoir 54 is supported, and in this reservoir is rotatably mounted the supply-roll 55, the shaft of which is provided with a pulley 56, which is driven by the belt 57 from the pulley 15. Also rotatable in the reservoir 54 is the distributingroll 58, driven by means of the gears 59 and 60, which distributes the glue over the surface of the supply-roll 55, the speed at which this roll 58 is driven being determined by the relative proportion of the gears 59 and 60. Below the reservoir 54 are bearings in which is journaled the shaft 61, having at one end the bevel-gear 62 and at the other end the pulley 63, driven by the belt 64 from the pulley 14. Also projecting from the frame 6 is the bracket-plate 65, having the upwardlyextending collar 66 and the pivoted clutchlatch support 67, and below this plate 65 is the bearing 68, also secured to the frame 6. In the collar 66 and the bearing 68 is journaled the vertical shaft 69, to the upper end of which is secured the frame 70, carrying the shaft 71, on which the glue-roll sections 72 and 73 are independently rotatable. On this shaft above the collar 66 is fixed the camplate 74, having downwardly-curving ends, and above the bearing 68 isfreely rotatable on said shaft the clutch mechanism 75 of any well-known construction, designed to be engaged by the key or latch 76 of the shaft 69 when this key or latch is released by the swinging outward of the pivoted latch-support 67, this clutch mechanism having the bevel-gear 77, which meshes with the gear 62 of the shaft 61, and the pivoted latch-support being controlled by the thumb-lever 78, pivoted on an extension of the bearing 68 and connected with the latch-support.

A box or carton similar to that shown in Fig. 5 of the drawings having been placed on the form 41, the flaps a a are turned down by the operator and rest on thesurface of the form, as shown in Fig. 4. The operator now presses the thumb-piece 78, thus moving the support 67 to permit the engagement of the key 76 with the clutch 75, which causes the rotation of shaft 69. The glue-roll frame 70 is swung on its axis, and the roll-sections 72 and 73, either or both, are brought over the outer surface of the flap 1), turning the same down onto the flaps act and applying glue to such outer surface. During this swinging of the glue-roll frame the cam 74 has worked under the pin 51 of the plate 50 and this pin and its plate have been permitted to drop approximately to the level of the flap Z) or to the plane in which the lower surface of the glueroll sections move The glue-roll sections, continuing their swinging movement, pass over the inner surface of the flap c and press it down onto the plate 50. As the application of glue to the flap 0 is completed the lower IIO Y jthe position shown in Fig. 2 as @116 glue'l'on comes to a rest on the supply-roll 55. Approximately at the time when the circuit of I the glue-roll has been completed the operator .depresses the lever 24, thus throwing the clutch mechanism into engagement to conmeet the sleeve with the drive-shaft 9. This shaft being thus caused to rotate, the cam- 18 permits the drawing of the arm 32 in one direction by the drawing action of the springs 34 34 on the carrier-arm 28 until the form 41,

withthe box, is brought under the cap 7, the

initial portion of this swinging movement of the carrier-arm bringing the outer surface of the flap 0 against the edge of the plate 50 and causing the turning down of said flap by the 20 plate untilthe glued surface of the flap is in approximate contact withthe outer surface of the flap b. When the form 41 has been brought under the cap 7, the bearing of the pin 33 isagainst the pressure-dwell 19 of the cam 18. The cam 16 has now rotated to a position where its acting portion works against the roller-bearing of the yoke 27 and forces the same upward, thrusting the end of the box against the under side of the cap 7 and compressing said end between the form and the cap to set the glued portions, the cam 16 then relieving the pressure and allowing the carrier to drop. As the cam 16 allows the dropping.

of the carrier the portion 21 of the cam 18 is brought opposite the bearing of the pin 33 and allows the springs 34 to draw the carrier to the position shown in dotted lines in Fig. 2 of the 1 drawings,and here another dwell 20 is brought opposite said pin 33. At the approach of the carrier-arm to this last position the engageable end of the ejector-arm 49 has engaged the ejector-block 36 and the cam 14 has been rotated, so that as the carrier reaches said position the cam portion 14 acts on the pin 44 of the arm 43 and through the connected 1nechanism actuates the arm 49 to sharply swing the same, and thus impel the ejector-rod 37 upward along its guideway and force the box 1 from the form 41, the cam 14 then permitting the arm 43 and its related mechanism to return to place, while the cam 18 acts against the bearing of the pin 33 to force the same back against the action of the springs34 and swinging the carrier-arm to the starting position. r By the use of the spur 38 in the end of the ejector-rod the box is heldfrom accidental displacement.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1 1. A box-machine, comprising a carrier-arm pivotally supported to swing and having a channel, an ejector movable in said channel,
